Franklin/Foxboro Line

Franklin/Foxboro Line is a commuter rail service operated by the Massachusetts Bay Transportation Authority (MBTA) in Greater Boston. It provides passenger rail service from South Station in Boston southwest to the terminus at Forge Park/495 in Franklin, with select trains continuing to a secondary terminus at Foxboro station. The line operates primarily on tracks owned by the Massachusetts Department of Transportation and shares its route for significant portions with the Providence/Stoughton Line and the Northeast Corridor.

History

The line's origins trace back to the Boston and Providence Railroad, which constructed the main line in the 1830s. Commuter service to Franklin was historically provided by the New York, New Haven and Hartford Railroad until the Penn Central Transportation Company era. Following the formation of the MBTA and the collapse of Conrail, dedicated Franklin service was inaugurated in 1988 after the state purchased the Franklin Branch from CSX Transportation. A major extension occurred in 2021 with the opening of service to Foxborough, utilizing the existing Framingham Secondary and a new connection built for Gillette Stadium events. This expansion was partly spurred by the U.S. national soccer team's use of the stadium and the success of the New England Revolution.

Route and stations

The line diverges from the Providence/Stoughton Line at the Readville junction in Hyde Park. The primary Franklin Branch serves stations including Dedham Corporate Center, Islington, Norwood Depot, Norwood Central, Windsor Gardens, Walpole, Plimptonville, and Norfolk, before terminating at Forge Park/495. The Foxboro Branch splits at Walpole, traveling east to serve Foxboro station adjacent to Gillette Stadium and Patriot Place. Key interchanges exist at South Station, Back Bay, and Ruggles for connections to the MBTA subway and other MBTA Commuter Rail lines like the Fairmount Line and the Needham Line.

Service and operations

Regular weekday service operates entirely to the Franklin terminus, while Foxboro service is typically limited to special events at Gillette Stadium, such as New England Patriots games, Taylor Swift concerts, and International Champions Cup soccer matches. Operations are managed by the MBTA's contract operator, Keolis. The line faces operational challenges due to single-track segments on the Franklin Branch, which limit frequency and require careful scheduling against freight movements operated by CSX Transportation. During peak hours, some trains originate or terminate at Readville to optimize equipment usage.

Rolling stock

The line is operated with a fleet of diesel-powered HSP-46 locomotives, primarily built by Wabtec, hauling push-pull trains of double-decker Kawasaki Heavy Industries coaches. This equipment is standardized across the MBTA Commuter Rail system and is maintained at the Southampton Street Yard and the Readville maintenance facility. The lack of electrification necessitates diesel operation for the entire route, though the shared trackage with the Northeast Corridor sees electric service from Amtrak' Acela and Northeast Regional trains.

Ridership and future plans

Pre-pandemic ridership exceeded 8,000 daily passengers, with 2023 averages recovering to approximately 5,600. The Foxborough extension has attracted significant event-day ridership, demonstrating the potential for transit-oriented development near Foxboro station. Future plans under the MBTA's Rail Vision initiative could include increased off-peak and weekend service frequencies. Long-term discussions have involved potential electrification as part of the Northeast Corridor modernization efforts and the integration of regional rail standards to improve performance and connectivity with Amtrak services at Route 128 station.
